Product details

The NEWTON LADY ISSAAC S offers intelligent control for all foot types. It works with your feet to improve their running form to the more efficient midfoot / forefoot running style. It forces you to land and strike correctly. Users may slow down in the beginning, but overtime it creates efficiency and compensate by allowing longer and easier runs. People who used it for a couple of weeks notice that it has eased their glute and hip pain. Some runners use the shoe as a variation for their marathon training runs. A consumer suffering from bad knee pains from tracking issues switched her shoes from Asics to LADY ISSAACS S. She felt no knee pain in half-marathon. It took her four months to get used to this shoe but she is so excited to come back running again.

Size and fit

The shoe provides a roomy toe box. Users might need to size up another half size from their street shoe size.

Outsole/ Midsole

The shoe’s carbon rubber outsole with traction tread increases durability. The beveled heel and toe helps guide runners easily into the midfoot/forefoot. The high-rebound EVA midsole ensure the light and flexible cushioning stays much longer and remains durable. The midfoot support chassis adds stability while medial posting offset pronation. The pronation control has been appreciated by runners in the longer runs. The shoe with the structure and design make users stay comfortable, and has helped runners increase speed and form.


The shoe uses highly-breathable closed mesh. The feet can stay cool and avoid swelling after long run. The slip-proof laces and heel-securing double eyelets along with metatarsal stretch panel can give feet the needed adjustment.
